Abstract

An interface device 3 is used to couple a first 101 and second 201 bi-directional signal path, such as 12C. The first bi-directional signal path 101 floats at a logic high level. Stations 110 coupled to the first signal path 101 are capable of generating a logic low level on the first signal path 101. To avoid that the system gets latched in a low state, a medium logic level is used on the first signal path 101. The interface device 3 generates the medium logic level on the first bi-directional signal path 101 in response to a low logic level on the second signal path 201. The interface device 3 generates on the second signal path 201 a low logic level in response to a low logic level on the first signal path and, otherwise, generates a high logic level. The stations 110 on the first signal path 101 detect the medium logic level and the low logic level as LOW and the high logic level as HIGH.
